The Supreme Court’s planned review of a major immigration detention fight is off the table for now after a New York pardon cut the case out from under it. At the center is a sharp clash over how long noncitizens can be held by ICE before due process requires a bond hearing, and whether convicted migrants facing deportation get that extra layer of court review.
The case had been set up to test a big question with real-world consequences: when does detention become so long that the Constitution steps in? The Second Circuit had already said that once immigration custody drags on for an “unreasonably long” period, a bond hearing is required under the Fifth Amendment’s due process clause.
That ruling put the Trump administration on the defensive, because the government argued that people who have committed deportable crimes should not get automatic bond hearings just because their detention lasts a while. The fight was not theoretical, either, since it involved detainees with criminal convictions and the government’s power to hold them while removal proceedings move ahead.
Then Gov. Kathy Hochul stepped in and changed the whole picture. She pardoned Keisy Guerrero Mariano, a lawful permanent resident from the Dominican Republic who had pleaded guilty to second-degree assault, and that move effectively wiped out the Supreme Court appeal tied to his case.
Mariano, identified in court filings as “Keisy GM,” had been detained by ICE after a 2015 assault conviction and spent close to two years in custody before getting out in 2022 under a COVID-era injunction. His pardon landed right when the brief was due, making the administration’s case lose its footing.
Solicitor General John Sauer later agreed that Genalo v. Black had become moot, but he also made clear the issue is not going away. The administration plans to look for another case, one it can use as a clean vehicle for getting the Supreme Court to answer the bond-hearing question in its 2026-27 term.
That matters because the Second Circuit’s 2024 decision has become a major obstacle for the government’s detention strategy. Under that ruling, a noncitizen cannot be kept in ICE custody indefinitely without a bond hearing once the detention crosses into what the court called an unreasonably long stretch.
The original case also involved Carol Williams Black, a Jamaican national with lawful status, whose circumstances added another layer to the dispute. But Black’s part of the appeal was also knocked out after the Supreme Court found his case moot because he had left the United States and said in a court filing that he would not return.
Critics of Hochul’s pardon argued that the move did more than help one man. In their view, it undercut a chance for the Supreme Court to settle a nationwide issue and gave a convicted offender a fast escape hatch from deportation proceedings.
Those critics did not hide their frustration. Iowa Solicitor General Eric Wessan blasted the pardon on X, calling it “Pretty wild to fully pardon an aggravated felon to (1) stop the felon from getting deported and (2) stop the Supreme Court from ruling on an issue. (Especially as this litigation has been going on for years),” and then added, “I wonder how many non-American felons Governors like Hochul will choose to fully pardon and free to avoid them facing consequences for their actions,” Wessan added.
The broader backdrop is the same old fight over immigration enforcement, court power, and public safety. ICE had first arrested Mariano in 2020, and officials viewed him as eligible for deportation because of the assault conviction and the time he had already served.
For the administration, the legal fight is about keeping custody rules tight enough to matter. For opponents, it is about making sure detention does not drift into something indefinite without a judge checking whether continued confinement is still justified.
